Printing machine coupling for propulsive coupling and uncoupling cylinders of e.g. 9-cylinder-printing unit, of rotary offset printing machine, has drive unit provided for axial shifting of hub between two positions

摘要

The coupling has a hub (16) formed such that the hub is axially shiftable on a drive pin (8) of a first cylinder (7) of a printing unit between two positions. A drive element (9) is mounted on the hub and provided for drive connection of the first cylinder of the printing unit with second and third cylinders (1, 2) of the printing unit. A drive unit is provided for axial shifting of the hub between the two positions, and the hub is shiftably mounted on an inner sleeve (20). An independent claim is also included for a printing unit of a printing machine.
